2N2712 noise transistors

[POLARIS at VAX1.Mankato.MSUS.EDU]

{
  Hi all!
I have been looking for the 2N3391 and 2N2712 transistors, but they doesent
seem to be produced anymore. Is there some equivalent transistors that can
be used instead of these two?
 
Thanks,=20  }

You can still get these from Midwest Analog Products - see :

BTW, they're apparently working on a MIDI-CV converter that might be even
cheaper than the PAIA one......
